Kudzima Nzira yeSimbi Pipe Deformation uye Crack

Austempering ndiko kuderedza deformation yesimbi nyere uye inobudirira nzira kudzima mutswe Jian, asi sei kushandisa nemazvo muitiro nzira kunofanira kwakavakirwa zvinonzwisisika musono simbi pombi zvinhu, saizi, kuoma uye kuoma, deformation zvinodiwa, uye chaiyo kushanda mamiriro. sarudzo ichave Isotherml inodzima matambudziko anoda kutariswa anopfupikiswa sezvizvi:
[1] Zvakadai sekabhoni simbi uye zvimwe yakaderera kuomarara simbi austempering quenching kuomesa, zvinofanira kuva zvakakodzera kuwedzera quenching tembiricha, H ndiko kuwedzera kugadzikana ari austenite kudzivisa uye kudzivirira kuitika kwepamusoro-tembiricha asiri magoko mune imwe. austempering quenching process transition's body.

[2] Austempering inorambidzwa simbi uye pombi saizi. Munguva yekudzimisa kudzima, iyo yakakosha musimboti ndeyekuona kuti shanduko haiitike isina musono simbi yekupisa tembiricha mukutonhora, uye nekudaro saizi yesimbi isina musono pombi simbi mamakisi uye kukanganisa kwakananga pamhando yekudzimisa kudzima, ruzhinji. zvinodikanwa zvekabhoni simbi isina musono pombi inoshanda ukobvu hunofanirwa kunge huri pasi pe5mm, ukobvu hunoshanda hweiyo alloy hunofanira kunge huri pasi pe30mm. Kubva pakuona kwekabhoni yemukati mu 0.4% kusvika 0.6% yekabhoni haikodzeri kudzikamisa, yakakwira kupfuura 0.6% kana kupfuura yekabhoni simbi kune austempering quenching.

[3] Tembiricha uye nguva zvinofanirwa kunge zvichibva pakuomesera kuomarara kwesimbi isina musono pombi kuita zvinodiwa, zvichireva simbi C-curve inotemerwa, musimboti, iyo yese austenite inoshandurwa kuita bainite, pane inotonhorera svikiro kazhinji nitrate yekugezera mhinduro kuitira kuti ave nechokwadi chekushisa kwakadzikama, chigadziro chekutonhora chinofanira kuwedzerwa mukati mekudzivirira kuwedzera kwekushisa kwepakati kunokanganisa kunaka kwekudzima. Etc. Mukuwedzera kureba kwenguva tembiricha inofanira kuronga shanduko inopera seamless simbi pombi sechiyereso, kushanda kwenguva refu kushanda kwakaderedzwa, uye naizvozvo kunofanira kutorwa zvakakomba.

[4] Kuomesa simbi inoomesa uye mamwe anogona kunge asina kushatirwa. Asi kune vamwe ^'muviri kuomeswa kweiyo workpiece, iyo yemukati yakasara austenite ichashandurwa mune inotevera mhepo inotonhorera maitiro ari martensite, inofanirwa kudzikamiswa, chinangwa ndechekubvisa brittleness uye kugadzikana seamless simbi mutongi, ona tembiricha yekudziya inofanira kunge iri. pasi pekushisa kwakanyanya.
